Please look at this bolt pattern
Can anyone tell me what bolt pattern this may be?
I bought a great downpipe from eBay before I bought my turbo thinking that the downpipe was a standard Ford 5 bolt pattern... And then I bought the turbo and found that the holes don't line up.
My downpipe will fit this .82 a/r turbine housing (below)... Note: the flying hole up top and that the bolt hole to the right of the wastegate port is a little further out?
Has anyone seen anything like this? and can you identify for me (what OE application? what model?) and do any of you guys know if I can get a .48 a/r housing with this pattern?

It looks like the standard 5-bolt but with an additional one up on the top and far right. I don't see a problem just using a general 5-bolt flange and ignoring the additional bolts. Good luck.

I agree. Looks like the pesky Mercedes bolt patern that seems to trick everyone.
Back when I had my Miata I originally had a T3/T61 to go on. It had this funky turbine housing as well :(

the bolt pattern on my Merc trubine housing has all the bolt holes spread out a little further (3/16-1/4") than the typical "ford" pattern.
All the holes on the turbine above line up with the typical ford style pattern, but the two outer holes do not- and those are the holes that mate with the wg/dp combo (in conjunction with the other three ford holes).

OH WAIT!!! Here's a picture of the downpipe and turbo that I actually have... I didn't remember that I had these.
Notice on the downpipe.. the "flying" top hole that's WAY up there. And the hole to the left of the wastegate flapper is also too far out. Is this the Mercedes bolt pattern?

I have no idea. It doesnt look like one. I've never seen the mercedes turbines in anything other than .48 stage 1 size. My stage 3 housing had to be machined from a stage 1.
They only exist in the aftermarket because a few shiploads of them were available for very cheap a few years back. People just rebuilt them with newer center sections and sold them for a profit. The upside is that I got a two very affordable turbos from the bargain.
You could port that WG hole out like another half an inch and nothign bad would happen.
